The simulated and measured real parts and amplitudes of electric fields.
(a) The simulated real parts of electric fields with practical parameters. (b) The simulated amplitudes of electric fields with practical parameters. (c,e,g) The measured real parts of electric fields at 10 GHz, 9.9 GHz and 9.8 GHz, respectively. (d,f,h) The measured amplitudes of electric fields at 10 GHz, 9.9 GHz and 9.8 GHz, respectively.
